PAVE Space secures $40M for orbital transfer vehicle development
▼ Summary
– PAVE Space, a Swiss startup spun out of a student rocketry program, has raised a $40 million seed round, one of the largest in European space history.
– The company is building orbital transfer vehicles (OTVs) to move satellites from their launch orbit to higher working orbits in under 24 hours, solving a “last-mile” logistics problem.
– Current solutions using electric propulsion for this transfer take six to twelve months, delaying revenue and increasing risks for satellite operators.
– The startup’s technology originates from a student team that built and flew Europe’s first reusable, vertically-landing rocket on a minimal budget.
– PAVE’s OTVs use storable bipropellant for rapid maneuverability, targeting both commercial and defense markets that need faster satellite repositioning.
A fundamental inefficiency is built into the satellite industry’s current model. While launch vehicles deliver payloads to the cheapest accessible point, low Earth orbit, the vast majority of operational satellites for communications, navigation, and defense operate far higher up, in geostationary orbit or medium Earth orbit. Bridging that gap, often called the last-mile logistics in space problem, currently relies on slow electric propulsion systems that can take up to a year. A Swiss startup now aims to slash that timeline to under a day.
PAVE Space, founded in Renens in 2024, has secured $40 million in seed funding to develop a fleet of rapid orbital transfer vehicles. This investment, among the largest seed rounds in European space history, was led by Visionaries Club and Creandum, with participation from Lombard Odier Investment Managers, Atlantic Labs, and several other venture firms. The capital will accelerate hardware development toward an in-orbit demonstration.
The company’s origins trace back to a pioneering student project at EPFL. In 2018, co-founders Julie Böhning, Jérémy Marciacq, and Simon Both launched the Gruyère Space Program. Their goal was to build Europe’s first student-made reusable rocket. By late 2024, their demonstrator, named Colibri, had completed 53 flights on a modest budget, proving the team’s technical prowess. That successful program provided the foundational technology and expertise for PAVE Space.
The commercial and strategic demand for faster orbital transit is intensifying. With over 12,000 active satellites and thousands more launched annually, operators cannot afford lengthy delays. A satellite stuck in transit for months generates no revenue and faces increasing risks from space debris and signal interference. For defense applications, the need is even more critical; the ability to rapidly reposition an asset in response to a threat is a capability current slow-moving propulsion cannot offer.
PAVE’s technical approach centers on using storable bipropellant propulsion. This contrasts with cryogenic fuels, which evaporate and are ill-suited for long orbital loiter times. The design trade-off accepts a somewhat lower specific impulse in exchange for indefinite fuel shelf life and greater operational flexibility, a key enabler for the vehicle’s mission profile.
The company is betting on a dual-use market strategy, a pattern already visible in the European space sector. Providers like Arianespace for launch or D-Orbit for in-space services have seen that credible European alternatives to American or Chinese systems can accelerate defense procurement. PAVE is applying this logic earlier in the value chain, at the orbital transfer layer, positioning itself to meet urgent commercial and national security needs with a rapid, domestically developed solution.
